Finally got that stubborn APU leak fixed after 3 days of chasing it
Had this APU on a 737 that kept leaking fuel from somewhere near the drain mast and nobody could find it. Senior guys looked at it, I looked at it, we ran it up maybe 5 times. Finally on day 3 I noticed a tiny wet spot on the bottom of a fuel line clamp that you could only see with a mirror on a stick. Turns out the rubber inside the clamp had split and let the line vibrate just enough to wear a pinhole. Replaced the clamp and the O rings on both ends and it passed the leak check first try. Felt good to solve something that stumped the whole shift. Anyone else had a gremlin like that where the fix was way simpler than you thought?

Respectfully, I'll say you got lucky and it wasn't really a complex issue. A split rubber clamp and a tiny pinhole is pretty basic stuff, not some mystery gremlin. The senior guys probably just dropped the ball on being thorough with their inspection, not some deep technical puzzle.

Oh man, that's a good one. Makes you wonder how many weird little fixes like that just get chalked up to gremlins because nobody wants to admit they missed something simple right in front of them.
